4130 fittings and flowline iron for the Marcellus and Utica

Appalachia produces nearly a third of US natural gas. We supply the flowline iron, chokes and 4130 parts its frac and flowback crews use, shipped through East Coast ports.

We supply Marcellus and Utica operators, completion and flowback companies and distributors with flowline iron and AISI 4130 parts: hammer unions, integral pups, plug valves, chokes and beans, API 6A flanges and 4130 pipe and fittings. Parts are made and tested in India and shipped through East Coast ports to Pittsburgh and the gas fields of Pennsylvania, Ohio and West Virginia.

What Appalachian gas wells ask of high-pressure iron

Appalachia, the Marcellus and Utica shales, produced 36.6 billion cubic feet of natural gas a day in 2025, 31% of US marketed production and more than any other region. Long horizontal gas wells are fractured at high pressure and flowed back with sand, so the same iron, valves and chokes as in Texas are in use, rigged up through hilly terrain and in cold winters.

Flowback is where the wear goes: sand cuts choke trim and plug valve inserts, so lined beans, spare trim and repair kits belong on the same order as the iron. Order low-temperature impact tests for parts rigged in winter, and the sour versions of parts for any well that produces hydrogen sulfide.

What Appalachian buyers order from us

Frac and flowback iron, and the chokes and trims that wear in gas flowback, lead Appalachian orders.

Getting parts to Pittsburgh and the well pads

Shipments for Appalachia come in through an East Coast port such as Baltimore, New York and New Jersey, or Norfolk, and go on by truck or rail to Pittsburgh and the well pads. The quotation can stop at an Indian port or at the US port, or your forwarder can carry it to your yard.

We have no US office or US stock: every order is made to your line list and ships from India with its EN 10204 3.1 certificates, packing list and commercial invoice. Your customs broker files the entry and confirms the duties. The steps, documents and marking rules are in ordering from India.

Working across time zones

India Standard Time is 9 hours 30 minutes ahead of Eastern time in summer and 10 hours 30 minutes ahead in winter, so our working day in India falls during your night.

Frequently asked questions

Do you ship through East Coast ports?

Yes. Quotations can be made to a port you name, or FOB India for your forwarder to route, so Appalachian orders need not travel through Houston.

Can we order spare trim with the chokes?

Yes. Beans, stem tips and seats, and plug valve repair kits can go on the same order, made to fit the bodies you run.
